In summary, p16INK4a, Notch1, and hTERC genes are abnormally expressed in HPV‐infected cervical diseases.14, 15, 16 However, there are large differences in the reports of p16INK4a‐positive expression rates in cervical tissues in different articles.17 We speculate that the expression levels of these three genes are possibly to be different in population expression. The gene discussed is CDKN2A; the disease is cervicitis.
